To all 'whom 'it may concern.:

Be it known that I, DERLAND E. SwnvnnAn'r, a citizen of the UnitedStates, residing at Missoula` in the county of Missoula and State ofMontana., have. invented certain new and usetul Improvements in aLoading and Unloading Truck, of which the following is a specification.

My invention relates to loading and unloading trucks, and moreespecially that class consisting ot' a dump body mounted to slide andtilt with respect to the chassis of a vehicle.

()ne of the objects of my invention resid-es in the construction of atruck having a removable dump body slidably mounted on the chassis of avehicle and means to tilt the said body at the rear end of the chassis.

A still further object of my invention resides in the provision of novelroller su J- porting means for a slidable dump bo y whereby the same maybe easily and conveniently removed from the chassis of a vehicle ortilted longitudinal with respect thereto.

W ith these objects in view and others which will be suggested as thenature and purpose of my invention are revealed in the followingspecification and drawing, wherein I have shown a preferred embodiment,it being understood that various changes in the precise structure may beresorted to without departing from the spirit of the invention.

FigureA is a perspective of a motor vehicle and the removable dump body.

Fig. 2 is a plan.

Fig. 3 is a view similar to Fig. 1 showing the dump body being tilted.

Fig. 4 is a perspective View showing the removable dump body and asupporting means therefor.

Fig. 5 is a view of the front supporting roller.

Fig. 6v shows the supporting bracket for the rear or end roller.

Figs. 7 8, 9, 10 and 11 are details.

Similar numerals in the specification referring to corresponding' partson the drawing, I have shown a motor vehicle 1 having the usual chassis2 on which a dumping body 3 is carried. The body 3 may be of any closedor open construction having vertical uprights 4, sides and front 5, 6and a bottom 7. The bottom of the body rests on transverse beams 8 whichconnect the longitudinally extending.,r side skids 9 and the centralskids 10.

In order to slidabl support the dump body on the chassis, lyprovide aseries ot' rollers, preferably three in number. rotatably supported insuitable boxings or bearings which are clamped to the chassis byU-shaped bolts 10a. The central bearings 11 and the supporting roller 12are positioned toi-ward of the rear wheels 13, the said bearings 11being slightly raised by shimming under the. bearings so that thecentral roller will be slightly higher than the front roller 14 and itsbearings 15.

The rear roller 16 and its bearings 17 are 1n turn slightly lower thanthe central roller and its bearings, it beingI apparent that by thisarrangement the body 3 may be easily and conveniently moved on thechassis.

Referring to Figs. 1 and 3 it will be seen that I provide a fourthroller 18 mounted 1n 'a solid boxing or bearings 19, secured to the topand ends of the chassis as at 20, 21 by suitable bolts 22. The fourthroller 18 extends somewhat beyond the end of the chassis and is slightlylower than the forward, 4first roller 14, the object in mounting therear roller lower being to insure that sufficient weight will be placedon the central roller when it is desired to unload.

Referring to Fig. 6 it will be seen that the front roller comprisesthree sections, the middle lor central portion 25 extending between theboxings or bearings, having its ends shrunk onto solid pieces of steelshafting 26. The shafting is turned down to the bore of the boxings andshort sections 27, 28 having squared ends 29 are shrunk onto collars 30keyed to the shaft 25, thereby permitting the ends of roller to beremoved from the boxing and also permits the use of solid cast bearings.The short sections 27, 28 extend outside the chassis properand supportthe side skids 9 of the dump The front roller is apertured to receiveapair of eyebolts 29 secured by nuts 30 and attached thereto are cables31, 32 which are connected as at33, 34 to the inner sides of the members9 at a point centrally of the body. A crank designated 35 has a squaredend 36 and a long right angle handle portion 37 whereby the crank mayrotate any one of the rollers and from either side as is obvious. Whennot in use, the crank 35 may be reversed from its operative position andits right angle handle vportion retained bestituting a lockin device forthe roller'.

When it is desired to transport an interchangeable lbody however, suchas indicated by Fig. 4, the truck is backed up to the said body resting,on a loading' horse H and the 35 is applied to the roller 37' on thehorse until the body engages the rolls on the truck. The crank 35 isthen applied to the "truck rolls and the cables 31, 32 attached to theside skids. By applying the' crank to the. front roll 4it will beapparent that said on or oil' the truck.

roll becomes a drum for the cables. To prevent the dump body fromslipping or moving transversely of theichassis, I provide a pair ofpivoted guards 38 on the sides of the skids 9 to engage the chassis, theguards sliding over the rollers as Athe body is moved when a is desiredi0 unload or' dump the body, the crank is of course, applied to theroller having the most weight thereon until the body is moved to thenext roller and so on.

From the foregoing it will be 'seen that I have provided a novelloadingand unload# ing truck which is capable of a variety of uses intransporting and handling bodies'of ,s g'reat weight and size. WhileIhave shown and described my infvention. and its ap-plication inhandling a dump body', it is obvious that it is also capable of otheruses.

From the foregoing description it will be seen that I have providedsimple and elicient means to accomplish the objects of the invent-ion,i-t being a preferred embodiment which I have found to be highlypractical, comprising but few :parts, whiich are not likely to get outof order, easily opera-ble by unskilled labor, and easily installed onany commercial tnuck chassis.

aving shown and described lmy invenl tion, what I now claim anddesire tosecure by Letters Patent of the U. S. is

What I claim is: 1. In a loading and unloading device, a

wheeled truck, a chassis, transverse rollers on said chassis supportedin front of the rear wheels'and similar transverse rollers rearwardly ofsald wheels, bearings for each i of said rollers clamped to the chassis,a removable dumlp body, means connecting the said dump body wlth theforemost roller,

. and means for loading thesaid bodyon the chassis by 'said fonemostroller.

2. In a loading and `unloading device, a wheeled truck, a chassis,rollers mounted on thechais in front of the rear wheels and additionalrollers on the chaissupported rearwardly of said wheels, all of saidrollers extending outside the chassis, a removable body, flexibleelements connecting said body with the fnont roller, said body'beingsupported by certain ofthe other rollers, and means to roll said bodI onand off the chais for the purpose speci ed.

3. In a loading and unloadin device, a wheeled truck, a chassis, laplura ity of rollers mounted transversely of said chassis, bearings onsaid chassis and supporting said rollers, each of said rollerscomprising a central shaft, collars keyed to said shaft and providedwith short stub shafts extending beyond the sides of the chais, cableretaining means on the front roller member only, a removable lbody,cables secured to said removable body .and said front roller,

and means to roll said body on the chassis Y y successively operatingthe said rollers.

` 4. In' a loading and unloading structure of the class described,awheeled truck, a chassis, a plurality of equally spaced transverserollers and bearings therefor mounted on said chassis, an iend roller, abearing for said end roller mounted on the top and end of said chassis,a removable dump body resting on certain of said rollers, guardspivotally secured to said body to prevent side movement thereof, andmeans to load or unload the said body by successively operating saidrollers.

5. In a loading and unloading device of the clam described, a wheeledtruck, a chassis, a plurality of rollers transversely mounted on saidchassis, each of said lrollers having squared ends, a removable. dumpbody resting on certain of said rollers, a removable crank for operatingany one of said rollers to roll said body on and ofi' the truck, and areversible crank cooperating with the squared ends of said rollers forlocking the same to pyi'event longitudinal movement of the body.

In testimony whereof I affix my signature hereto.

DERLAND E. SWINEHART.
